DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slicing apparatus for food and the like and a blade used for the slicing apparatus.

[0002]

2. Description of the Related Art As shown in FIG. 1, in a slicing apparatus 1 (slicer) for thinly slicing foods or the like, a feed plate 3 is formed on an upper surface of an apparatus main body 4;
The food is sliced while being fed by the feed plate 3 toward a rotary blade called a blade 2. Here, if oil or dirt adheres to the blade 2, the sharpness is reduced. When the bread is sliced with the blade 2 having such reduced sharpness, the cut edge becomes rough as if it were cut, and the appearance is poor. In addition, if the rough cut is left as it is, the cut is quicker than the smooth cut, and the taste is reduced in a short time. In addition, when slicing a seaweed roll or the like, if the crushed rice grains adhere to the surface of the blade 2 in a paste-like manner and the sharpness is reduced, the appearance of the cut end also becomes poor.

Therefore, conventionally, the operation of the slicing apparatus 1 is stopped every time dirt or crushed rice grains adhere to the blade 2, and the dirt or crushed rice grains are wiped off with a wet cloth.

[0004]

However, since the dirt and crushed rice grains adhered to the blade 2 cannot be easily wiped off with a wet cloth, regenerating the blade 2 requires considerable time and effort. There is a problem that efficiency is low.
Further, just because the dirt and the crushed rice grains adhered to the blade 2 cannot be easily wiped off, excessive force is applied and the blade 2
Touching the cutting edge is dangerous. In addition, not only the blade 2 but also the surface of the apparatus main body 2 to which dirt and rice grains adhere are the same. It is troublesome to frequently wipe the surface of the apparatus main body 2 to keep it clean.

Accordingly, an object of the present invention is to provide a slicing apparatus and a slicing apparatus capable of removing oil stains and crushed rice grains without any trouble even if they adhere. It is to provide a blade to be used.

[0006]

According to the present invention, there is provided a slicing apparatus in which a blade for cutting an article such as food is supported on an apparatus main body. A layer containing a photocatalytic material such as

In the present invention, the surface of a normal metal or resin has a contact angle of water of several degrees to several tens of degrees depending on the material and surface condition. On the other hand, when a layer containing a photocatalytic material is formed on the blade surface using a coating agent in which a silicone resin or the like and titanium oxide as a photocatalytic material are combined, and the surface of the blade is sufficiently irradiated, the water on the surface is reduced. Is almost 0 degrees. This phenomenon is called a superhydrophilic phenomenon, and such a property is called superhydrophilicity. The surface of the blade imparted with super-hydrophilicity in this way is more easily adapted to water than oil stains. Therefore, oil stains are less likely to adhere to the surface of the superhydrophilized blade, so that sharpness is maintained. In addition, even if oil stains adhere to the blade surface, the oil stains can be easily wiped off with a cloth soaked in water. Since the oil stain is separated, the oil stain can be easily removed. Furthermore, not only oil stains, but also crushed rice grains adhere to the blade in a glue-like manner, since the affinity between the surface of the plate and water is high, crushed rice grains can be easily removed. Moreover, the layer containing the photocatalytic material, once superhydrophilized by ultraviolet irradiation,
The advantage is that the effect is maintained for several tens of hours, and even if the superhydrophilicity is reduced, if the superhydrophilicity is exposed to sunlight or ultraviolet light and irradiated with ultraviolet rays, the reduced superhydrophilicity is restored. There is.

In another aspect of the present invention, in a slicing apparatus in which a blade for cutting an article such as food is supported by an apparatus main body, the surface of the apparatus main body includes a photocatalytic material such as titanium oxide. It is characterized in that a layer is formed. According to such an embodiment, there is an advantage that the apparatus main body can be kept clean, for example, oil stains and other dirt attached to the apparatus main body of the slicing apparatus can be easily removed.

In the present invention, a layer containing a photocatalytic material may be formed on the surface of the replacement blade of the slicing apparatus.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a slice apparatus to which the present invention is applied will be described.

FIG. 1 is an external view of the slicing apparatus. The slicing apparatus 1 shown in FIG. 1 is for slicing bread or the like, and a feed plate 3 is formed on an upper surface of the apparatus main body 4. The feed plate 3 feeds the bread toward a blade 2 (rotary blade). Slicing.

In this embodiment, first, a layer containing a photocatalytic material such as titanium oxide is formed on the surface of the blade 2. Further, a layer containing a photocatalytic material such as titanium oxide is also formed on the surface of the device main body 4.

The layer containing such a photocatalytic material is formed by applying a coating agent comprising a combination of a silicone resin and a titanium oxide as a photocatalytic material. Is almost 0 degrees.

That is, the surface of the substrate on which the layer containing the photocatalytic material is not formed has a contact angle of water of several degrees to several tens degrees, whereas the surface of the resin has a contact angle of several degrees as shown in FIG. After a layer T containing a photocatalytic material is formed, for example, to a thickness of about 0.1 μm to 50 μm using a coating agent combining titanium oxide, which is a photocatalytic material, and a silicone resin, and then sufficiently irradiated with ultraviolet rays, the resin surface (base The contact angle of water on the surface of the material R) is almost 0 degrees. The reason is that the surface of the base material R is covered with the hydrophobic substance R0 and has a property of repelling water, whereas the photocatalytic material decomposes the hydrophobic substance R0 by irradiating ultraviolet rays, and the thin water This is considered to be for stably forming a molecular layer.

Accordingly, dirt adhering to the surface of the blade 2 having no superhydrophilic property or the surface of the apparatus main body 4 cannot be removed without using a detergent or the like. If the surface of the apparatus main body 4 is made super-hydrophilic, the surface of the blade 2 and the surface of the apparatus main body 4 are more easily adapted to water than oil stains. For this reason, since oil stains do not easily adhere to the surface of the superhydrophilized blade 2, sharp sharpness is maintained. In addition, even if oil stains adhere to the surface of the blade 2, the oil stains can be easily wiped off with a cloth soaked in water. Oil stains can be easily removed from the surface. Therefore, it is not necessary to wipe off dirt adhering to the blade 2 with force, and the danger of injury due to touching the blade edge of the blade 2 can be eliminated. Further, not only oil stains, but also rice grains crushed when slicing laver rolls adhere to the blade 2 in a glue-like manner, since the affinity of the surface of the plate 2 and water is high, It can be easily removed. The same applies to the surface of the apparatus main body 2; oil stains and other stains can be easily removed and the stains can be kept clean. Moreover, once the layer containing the photocatalytic material is made superhydrophilic by irradiation with ultraviolet light, its effect is maintained for several tens of hours. If you irradiate
There is an advantage that the reduced superhydrophilicity is restored. Also,
Titanium oxide, which is a photocatalytic material, is currently used for packaging materials for foods and the like, and even if mixed in any way, it is safe with little danger. In addition, it has been recognized that titanium oxide itself has an antibacterial effect, and it can be expected that bacteria and fungi can be prevented from adhering to the surface of the layer containing the photocatalytic material. In particular, since titanium oxide and the like are available at a low cost and silicone resin is also inexpensive, superhydrophilicity can be imparted to the surface of the blade 2 and the surface of the apparatus main body 4 at low cost.

Further, in order to improve the existing slicing apparatus, a coating containing a combination of silicone resin and titanium oxide may be applied to the surface of the blade 2 or the apparatus main body 4 to form a layer containing a catalytic material. .

When a layer containing a photocatalytic material is coated on the surface, it is necessary to irradiate ultraviolet rays as described above in order to make the layer super-hydrophilic. Ultraviolet irradiation means such as a lamp may be provided. Such an ultraviolet lamp can be obtained relatively inexpensively. Even in this case, once the layer containing the catalytic material has been made superhydrophilic by irradiation with ultraviolet light, its effect is maintained for several tens of hours, so that it is not necessary to keep the ultraviolet lamp lit continuously, By turning off the light, ultraviolet rays can be prevented from damaging the retina of the worker. Further, when the ultraviolet rays are regularly irradiated, there is an effect that the blade 2 or the apparatus main body 4 can be sterilized.

The surface of the blade 2 or the surface of the apparatus main body 4 may be imparted with sterility by a combination of the photocatalytic material and a sterile material such as an organic acid. This bactericidal property forms an environment in which various bacteria are unlikely to exist, thereby forming an environment in which bacteria do not multiply, and does not necessarily have a bactericidal action itself. As a specific embodiment, there is a method of kneading a silicon resin with a photocatalytic material and a disinfectant material.

[0019]

As described above, according to the present invention, since a layer containing a photocatalytic material is formed on the surfaces of the blades of the slicing apparatus and the apparatus main body, oil stains and the like hardly adhere to these surfaces. Therefore, the sharpness of the blade and the clean state of the device can be maintained for a long time. In addition, the attached dirt can be easily removed only by washing with water, which is sanitary.
Therefore, the slicing apparatus to which the present invention is applied is suitable for food.
